UNITED STATES PATENT OFFICE.

HART HARRIS, OF WASHINGTON, PENNSYLVANIA.

LU BRICATOR.

srncrrrcarron forming part of Letters Patent No. 701,567, dated June 9',1902.

Application filed May 31,1901.

To all whom it may concern:

Be it known that I, HART HARRIS, a citizen of the United States,residing at Washington, in the county of Washington and State ofPennsylvania, have invented a new and useful Lubricator, of which thefollowing is a This invention relates to lubricators, more particularlyto those employed in lubricating steam-cylinders and other apparatusemploying steam; and the invention consists in the construction,combination, and arrangement of parts, as hereinafter shown anddescribed, and specifically pointed out in the claim.

In the drawings, Figure 1 is a vertical sectional elevation. Fig. 2is aside elevation of the upper part of the device, illustrating theconstruction of the vent-valveoperating The casing or shell 1 will beattached to the steam chest or cylinder of a steam-engine, steam-pump,or other apparatus by its lower end, as at 2. The casing will beprovided with a closure 3 at its upper end, the closure being providedwith stop-cock 4: and rising into a funnel 5 above the plug of the cock,as shown. By this means the oil will be introduced into the casing andthe whole interior of the casing also rendered accessible by removingthe closure. The closure 3 will preferably be connected to the casing bybeingscrewed therein, as shown. Rising into the casing from its lowerend is a tube 6 and connecting with the cylinder or steam-chest withwhich the casing is engaged and preferably enlarged at its upper end toprovide a cavity for a packing 7. Fitting .down into the upper end ofthe tube 6 is a smaller tube 8, with its upper end turned over andcontracted at its outlet 9, so as to cause the outlet9 to opendownwardly. Y

10 is a gland engaging the upper end of the tube 6 and adapted tocompress the packing 7 around the tube 8 and forming a stuffingboxbetween the tubes. 6 and 8. By this means the tube 8 is supported inthetube 6 with sutficient-force to resist any strains to which it would besubjected when in use. The tube 8 can be readily adjusted vertically byremoving the closure 3 and applying a Serial No. 62,607. (No model.)

pulling or pushing force upon it sufficient to overcome the resistanceof the packing 7.

11 is a petcock in -thelower part of the casing to provide for theremoval of the condensed water when required.

12 is a vent-gvalve in the closure 3 and adapted to be maintained,normally closed by a spring 13 and with a stem 14 rising upward andadapted to be engaged by a cam 15 on the stem 16 of the stop-cock 4, sothat when the plug of the stop-cock isturned to open it the cam willforce the valve 12 open, and thus provide a vent to the casing to permitthe escape'of the air as the oil flowsin. the casing is recharged theclosing of the stop-cock will likewise turn the cam 15 and release thevent-valve, "which will at once be closed by its spring 13.

The oil .will be allowed to flow into the casing until it rises nearlyto the outlet 9 of the curved tube 8, as indicated by dotted lines inFig. 1. Then when the steam from the cylinder escapes through the tubes6 and 8 into the space above the oil'it will be condensed, and water ofcondensation, being of greater specific gravity than the oil, will sinkthrough the oil and cause the latter. to rise and flow over intothetubes 6 and 8, andthus find its way to the mechanism with which thedevice is connected and automatically lubricate them. The tube 8 may beadjusted in accordance withthe quantity of oil and condensed steam inthe lubricator, the withdrawal of a quantity of water through thepetcock necessitating adepression of the tube unless an equal amount ofoil be added.

By contracting theoutlet 9 ofthe pipe 8 an eifectual means is provided.for preventing the cloggingof; the pipe, as any small foreignparticle'swhich would pass through the contracted portion 9 would freely passthrough the larger area of the pipe without clogging it.

What I claim as new is r In a lubricator having a receptacle for theoil, means for feeding the oil from said receptacle, a removable closureto said receptacle enlarged into a funnel and a-stop-co'ck between saidfunnel and receptacle, a ventvalve in said closure adapted to releaseair Then when from said receptacle, and having a stem rismy own I havehereto affixed my signature in ing through said closure, and a cam uponthe the presence of twowitnesses.

pln of said stop-cock adapted to en age said i valae-stem, and open said,valve WTIGII said HART HARRIS 5 Valve-plug is actuated, substantiallyas de- \Vitnesses:
